aarch64: Use xzr instead of x31 in the ASM code
Officially, register X31 does not exist. The code is zeroing out a location
and thus actually needs XZR.
LLVM seems to automatically translate X31 into XZR when compiling the code,
but GCC (tested 7.3.0) refuses to accept the instruction:
../../third_party/crashpad/crashpad/util/misc/capture_context_linux.S: Assembler messages:
../../third_party/crashpad/crashpad/util/misc/capture_context_linux.S:291: Error: operand 1 must be an integer register -- `str x31,[x0,#0xb0]'
